How to select data from two sql tables with special field layout - sql-server

I have two tables as shown in the example. Now I want to select the data in the format presented in the comment lines below.
create table cust (nbr varchar(8))
create table data (nbr varchar(8),fld varchar(8),val varchar(8))
insert into cust (nbr) values ('AA')
insert into data (nbr,fld,val) values ('AA','1','one')
insert into data (nbr,fld,val) values ('AA','2','two')
insert into data (nbr,fld,val) values ('AA','3','three')
insert into data (nbr,fld,val) values ('AA','1','uno')
insert into data (nbr,fld,val) values ('AA','2','dos')
insert into data (nbr,fld,val) values ('AA','3','tres')
select * from cust
select * from data
drop table cust
drop table data
-- AA, One, Two, Three
-- AA, Uno, Dos, Tres
Any ideas how to join these tables to get the desired output.

At the moment you don't have anything in the data table which would allow you to group the rows into anything you can work with. If you add a languageID column to the data table as suggested by #avery_larry, you could write your select as follows:
create table cust (nbr varchar(8))
create table data (nbr varchar(8),fld varchar(8),val varchar(8), languageID int)
insert into cust (nbr) values ('AA')
insert into data (nbr,fld,val, languageID) values ('AA','1','one', 1)
insert into data (nbr,fld,val, languageID) values ('AA','2','two', 1)
insert into data (nbr,fld,val, languageID) values ('AA','3','three', 1)
insert into data (nbr,fld,val, languageID) values ('AA','1','uno', 2)
insert into data (nbr,fld,val, languageID) values ('AA','2','dos', 2)
insert into data (nbr,fld,val, languageID) values ('AA','3','tres', 2);
select * from cust;
select * from data;
with data_cte(nbr, languageID)
as
(
select nbr, languageID
from data with (nolock)
group by nbr, languageID
)
select c.nbr,
SUBSTRING(
(
SELECT ','+d.val AS [text()]
FROM [data] d
WHERE d.nbr = dc.nbr and d.languageID = dc.languageID
ORDER BY d.fld
FOR XML PATH ('')
), 2, 1000) as 'Values'
from data_cte dc
inner join cust c on c.nbr = dc.nbr;
drop table cust
drop table data
The sql for concatenating the strings was taken from this post How to concatenate text from multiple rows into a single text string in SQL server?, with a slight tweek to add the with.
Hope this helps.

Display few specific rows always at the top

I want to display a few specific Rows always at top of the query results.
For example: Cities Table. Columns: City ID, City Name
I want to fetch Query result where Mumbai, Bangalore, Chennai, Hyderabad should display at the top always.
1st way:
I can insert these records first in the table so that they will get displayed always at the top.
But, this way will not work if any other city gets added after a few months that I also want to display at the top.
Use an iif in your order by clause:
SELECT CityId, CityName
FROM Cities
ORDER BY IIF(CityName IN ('Mumbai', 'Bangalore', 'Chennai', 'Hyderabad'), 0, 1), CityName
You can't rely on the order in which you've entered the records to the table, because database tables are unsorted by nature, and without an order by clause, the order of the result set will be arbitrary.
For more information, read The “Natural order” misconception on my blog.
Try this:
Declare #t table (cityID int,cityname nvarchar(50))
insert into #t values (2,'Gujrat')
insert into #t values (4,'Surat')
insert into #t values (6,'Mumbai')
insert into #t values (3,'Bangalore')
insert into #t values (5,'Chennai')
insert into #t values (1,'Hyderabad')
select * from #t
order by case when cityname in ('Mumbai','Bangalore','Chennai','Hyderabad') then 0 else 1 END
Clean way of doing this,
Declare #t table (cityID int,cityname nvarchar(50))
Declare #DesireOrder table (id int identity,CityID int) -- instead of cityname
insert into #DesireOrder values (6),(3),(5),(1)
insert into #t values (2,'Gujrat')
insert into #t values (4,'Surat')
insert into #t values (6,'Mumbai')
insert into #t values (3,'Bangalore')
insert into #t values (5,'Chennai')
insert into #t values (1,'Hyderabad')
insert into #t values (8,'Delhi')
insert into #t values (7,'New Delhi')
select t.* from #t t
left join DesireOrder O on t.cityid=O.cityid
order by o.id,t.cityID
Main idea is #DesireOrder, rest you can implement as per your requirement.

How to get Current Year and Previous Year values as Columns

Can any body please tell me about below case.
I have fact table which has datekey, I have bridge table which has Datekey and PYdatekey( PYDatekey represents last year value).
When I want current year value, I am joining with FactTable.DateKey = BridgeTable.DateKey, for Last year values FactTable.DateKey=BridgeTable.PYDateKey.
I am writing two separate queries doing union all to get these values as rows.
But now I need to get these values as columns. Please suggest how to achieve this.
You can join to FactTable twice to get the previous and current data separately.
Use LEFT JOIN in case Datekey and/or PYdatekey is not required in BridgeTable.
--Sample data
CREATE TABLE BridgeTable (Datekey int, PYdatekey int)
CREATE TABLE FactTable (datekey int, SomeField varchar(100))
INSERT INTO FactTable VALUES (1, 'A')
INSERT INTO FactTable VALUES (2, 'B')
INSERT INTO BridgeTable VALUES (1, 2)
INSERT INTO BridgeTable VALUES (1, null)
INSERT INTO BridgeTable VALUES (null, 2)
--Query
SELECT PreviousFacts.SomeField AS Previous_SomeField, CurrentFacts.SomeField AS Current_SomeField --Or whatever columns you need
FROM BridgeTable
LEFT JOIN FactTable PreviousFacts ON BridgeTable.PYdatekey = PreviousFacts.DateKey
LEFT JOIN FactTable CurrentFacts ON BridgeTable.Datekey = CurrentFacts.DateKey

T-SQL: Two Level Aggregation in Same Query

I have a query that joins a master and a detail table. Master table records are duplicated in results as expected. I get aggregation on detail table an it works fine. But I also need another aggregation on master table at the same time. But as master table is duplicated, aggregation results are duplicated too.
I want to demonstrate this situation as below;
If Object_Id('tempdb..#data') Is Not Null Drop Table #data
Create Table #data (Id int, GroupId int, Value int)
If Object_Id('tempdb..#groups') Is Not Null Drop Table #groups
Create Table #groups (Id int, Value int)
/* insert groups */
Insert #groups (Id, Value)
Values (1,100), (2,200), (3, 200)
/* insert data */
Insert #data (Id, GroupId, Value)
Values (1,1,10),
(2,1,20),
(3,2,50),
(4,2,60),
(5,2,70),
(6,3,90)
My select query is
Select Sum(data.Value) As Data_Value,
Sum(groups.Value) As Group_Value
From #data data
Inner Join #groups groups On groups.Id = data.GroupId
The result is;
Data_Value Group_Value
300 1000
Expected result is;
Data_Value Group_Value
300 500
Please note that, derived table or sub-query is not an option. Also Sum(Distinct groups.Value) is not suitable for my case.
If I am not wrong, you just want to sum value column of both table and show it in a single row. in that case you don't need to join those just select the sum as a column like :
SELECT (SELECT SUM(VALUE) AS Data_Value FROM #DATA),
(SELECT SUM(VALUE) AS Group_Value FROM #groups)
SELECT
(
Select Sum(d.Value) From #data d
WHERE EXISTS (SELECT 1 FROM #groups WHERE Id = d.GroupId )
) AS Data_Value
,(
SELECT Sum( g.Value) FROM #groups g
WHERE EXISTS (SELECT 1 FROM #data WHERE GroupId = g.Id)
) AS Group_Value
I'm not sure what you are looking for. But it seems like you want the value from one group and the collected value that represents a group in the data table.
In that case I would suggest something like this.
select Sum(t.Data_Value) as Data_Value, Sum(t.Group_Value) as Group_Value
from
(select Sum(data.Value) As Data_Value, groups.Value As Group_Value
from data
inner join groups on groups.Id = data.GroupId
group by groups.Id, groups.Value)
as t
The edit should do the trick for you.

sqlserver assigning last inserted Id to another column in one query

when this query is executed
DECLARE #Temp TABLE (ID INT IDENTITY,Name VARCHAR(50),ID2 INT NULL)
INSERT INTO #Temp ([Name]) VALUES ('Ali')
UPDATE #Temp SET ID2= (SELECT SCOPE_IDENTITY()) WHERE [ID]=(SELECT SCOPE_IDENTITY())
INSERT INTO #Temp ([Name]) VALUES ('Veli')
UPDATE #Temp SET ID2= (SELECT SCOPE_IDENTITY()) WHERE [ID]=(SELECT SCOPE_IDENTITY())
SELECT * FROM #Temp
We can get this table
ID-NAME-ID2
1 - Ali - 1
2 - Veli - 2
is there a way to do this in one insert query ( Assigning inserted id to another column without using idendity property in that column) ?
thanks a lot.
You want to make it a computed column like below
create TABLE Temp(ID INT IDENTITY,Name
VARCHAR(50),
ID2 AS ID PERSISTED);
Then insert rows ... your ID values will be persisted in ID2 column
INSERT INTO Temp ([Name])
VALUES ('Ali');
INSERT INTO Temp ([Name])
VALUES ('Veli');
INSERT INTO Temp ([Name])
VALUES ('Neli');
Which will results in
See a demo fiddle here http://sqlfiddle.com/#!3/59fca/1
EDIT:
If you can't change your table structure then the only way insert ID value to ID2 column is the way you are currently doing it cause in same insert statement the identity value is still not available and so it will be null.

Insert multiple rows WITHOUT repeating the "INSERT INTO ..." part of the statement?

I know I've done this before years ago, but I can't remember the syntax, and I can't find it anywhere due to pulling up tons of help docs and articles about "bulk imports".
Here's what I want to do, but the syntax is not exactly right... please, someone who has done this before, help me out :)
INSERT INTO dbo.MyTable (ID, Name)
VALUES (123, 'Timmy'),
(124, 'Jonny'),
(125, 'Sally')
I know that this is close to the right syntax. I might need the word "BULK" in there, or something, I can't remember. Any idea?
I need this for a SQL Server 2005 database. I've tried this code, to no avail:
DECLARE #blah TABLE
(
ID INT NOT NULL PRIMARY KEY,
Name VARCHAR(100) NOT NULL
)
INSERT INTO #blah (ID, Name)
VALUES (123, 'Timmy')
VALUES (124, 'Jonny')
VALUES (125, 'Sally')
SELECT * FROM #blah
I'm getting Incorrect syntax near the keyword 'VALUES'.
Your syntax almost works in SQL Server 2008 (but not in SQL Server 20051):
CREATE TABLE MyTable (id int, name char(10));
INSERT INTO MyTable (id, name) VALUES (1, 'Bob'), (2, 'Peter'), (3, 'Joe');
SELECT * FROM MyTable;
id | name
---+---------
1 | Bob
2 | Peter
3 | Joe
1 When the question was answered, it was not made evident that the question was referring to SQL Server 2005. I am leaving this answer here, since I believe it is still relevant.
INSERT INTO dbo.MyTable (ID, Name)
SELECT 123, 'Timmy'
UNION ALL
SELECT 124, 'Jonny'
UNION ALL
SELECT 125, 'Sally'
For SQL Server 2008, can do it in one VALUES clause exactly as per the statement in your question (you just need to add a comma to separate each values statement)...
If your data is already in your database you can do:
INSERT INTO MyTable(ID, Name)
SELECT ID, NAME FROM OtherTable
If you need to hard code the data then SQL 2008 and later versions let you do the following...
INSERT INTO MyTable (Name, ID)
VALUES ('First',1),
('Second',2),
('Third',3),
('Fourth',4),
('Fifth',5)
Using INSERT INTO ... VALUES syntax like in Daniel Vassallo's answer
there is one annoying limitation:
From MSDN
The maximum number of rows that can be constructed by inserting rows directly in the VALUES list is 1000
The easiest way to omit this limitation is to use derived table like:
INSERT INTO dbo.Mytable(ID, Name)
SELECT ID, Name
FROM (
VALUES (1, 'a'),
(2, 'b'),
--...
-- more than 1000 rows
)sub (ID, Name);
LiveDemo
This will work starting from SQL Server 2008+
This will achieve what you're asking about:
INSERT INTO table1 (ID, Name)
VALUES (123, 'Timmy'),
(124, 'Jonny'),
(125, 'Sally');
For future developers, you can also insert from another table:
INSERT INTO table1 (ID, Name)
SELECT
ID,
Name
FROM table2
Or even from multiple tables:
INSERT INTO table1 (column2, column3)
SELECT
t2.column,
t3.column
FROM table2 t2
INNER JOIN table3 t3
ON t2.ID = t3.ID
You could do this (ugly but it works):
INSERT INTO dbo.MyTable (ID, Name)
select * from
(
select 123, 'Timmy'
union all
select 124, 'Jonny'
union all
select 125, 'Sally'
...
) x
You can use a union:
INSERT INTO dbo.MyTable (ID, Name)
SELECT ID, Name FROM (
SELECT 123, 'Timmy'
UNION ALL
SELECT 124, 'Jonny'
UNION ALL
SELECT 125, 'Sally'
) AS X (ID, Name)
This looks OK for SQL Server 2008. For SS2005 & earlier, you need to repeat the VALUES statement.
INSERT INTO dbo.MyTable (ID, Name)
VALUES (123, 'Timmy')
VALUES (124, 'Jonny')
VALUES (125, 'Sally')
EDIT:: My bad. You have to repeat the 'INSERT INTO' for each row in SS2005.
INSERT INTO dbo.MyTable (ID, Name)
VALUES (123, 'Timmy')
INSERT INTO dbo.MyTable (ID, Name)
VALUES (124, 'Jonny')
INSERT INTO dbo.MyTable (ID, Name)
VALUES (125, 'Sally')
It would be easier to use XML in SQL Server to insert multiple rows otherwise it becomes very tedious.

Copy the following code into sql server to view a sample.
declare #test nvarchar(max)
set #test = '<topic><dialog id="1" answerId="41">
<comment>comment 1</comment>
</dialog>
<dialog id="2" answerId="42" >
<comment>comment 2</comment>
</dialog>
<dialog id="3" answerId="43" >
<comment>comment 3</comment>
</dialog>
</topic>'
declare #testxml xml
set #testxml = cast(#test as xml)
declare #answerTemp Table(dialogid int, answerid int, comment varchar(1000))
insert #answerTemp
SELECT ParamValues.ID.value('#id','int') ,
ParamValues.ID.value('#answerId','int') ,
ParamValues.ID.value('(comment)[1]','VARCHAR(1000)')
FROM #testxml.nodes('topic/dialog') as ParamValues(ID)
USE YourDB
GO
INSERT INTO MyTable (FirstCol, SecondCol)
SELECT 'First' ,1
UNION ALL
SELECT 'Second' ,2
UNION ALL
SELECT 'Third' ,3
UNION ALL
SELECT 'Fourth' ,4
UNION ALL
SELECT 'Fifth' ,5
GO
OR YOU CAN USE ANOTHER WAY
INSERT INTO MyTable (FirstCol, SecondCol)
VALUES
('First',1),
('Second',2),
('Third',3),
('Fourth',4),
('Fifth',5)
I've been using the following:
INSERT INTO [TableName] (ID, Name)
values (NEWID(), NEWID())
GO 10
It will add ten rows with unique GUIDs for ID and Name.
Note: do not end the last line (GO 10) with ';' because it will throw error: A fatal scripting error occurred. Incorrect syntax was encountered while parsing GO.
Corresponding to INSERT (Transact-SQL) (SQL Server 2005) you can't omit INSERT INTO dbo.Blah and have to specify it every time or use another syntax/approach,
In PostgreSQL, you can do it as follows;
A generic example for a 2 column table;
INSERT INTO <table_name_here>
(<column_1>, <column_2>)
VALUES
(<column_1_value>, <column_2_value>),
(<column_1_value>, <column_2_value>),
(<column_1_value>, <column_2_value>),
...
(<column_1_value>, <column_2_value>);
See the real world example here;
A - Create the table
CREATE TABLE Worker
(
id serial primary key,
code varchar(256) null,
message text null
);
B - Insert bulk values
INSERT INTO Worker
(code, message)
VALUES
('a1', 'this is the first message'),
('a2', 'this is the second message'),
('a3', 'this is the third message'),
('a4', 'this is the fourth message'),
('a5', 'this is the fifth message'),
('a6', 'this is the sixth message');
This is working very fast,and efficient in SQL.
Suppose you have Table Sample with 4 column a,b,c,d where a,b,d are int and c column is Varchar(50).
CREATE TABLE [dbo].[Sample](
[a] [int] NULL,
[b] [int] NULL,
[c] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[D] [int] NULL
)
So you cant inset multiple records in this table using following query without repeating insert statement,
DECLARE #LIST VARCHAR(MAX)
SET #LIST='SELECT 1, 1, ''Charan Ghate'',11
SELECT 2,2, ''Mahesh More'',12
SELECT 3,3,''Mahesh Nikam'',13
SELECT 4,4, ''Jay Kadam'',14'
INSERT SAMPLE (a, b, c,d) EXEC(#LIST)
Also With C# using SqlBulkCopy bulkcopy = new SqlBulkCopy(con)
You can insert 10 rows at a time
DataTable dt = new DataTable();
dt.Columns.Add("a");
dt.Columns.Add("b");
dt.Columns.Add("c");
dt.Columns.Add("d");
for (int i = 0; i < 10; i++)
{
DataRow dr = dt.NewRow();
dr["a"] = 1;
dr["b"] = 2;
dr["c"] = "Charan";
dr["d"] = 4;
dt.Rows.Add(dr);
}
SqlConnection con = new SqlConnection("Connection String");
using (SqlBulkCopy bulkcopy = new SqlBulkCopy(con))
{
con.Open();
bulkcopy.DestinationTableName = "Sample";
bulkcopy.WriteToServer(dt);
con.Close();
}
Others here have suggested a couple multi-record syntaxes. Expounding upon that, I suggest you insert into a temp table first, and insert your main table from there.
The reason for this is loading the data from a query can take longer, and you may end up locking the table or pages longer than is necessary, which slows down other queries running against that table.
-- Make a temp table with the needed columns
select top 0 *
into #temp
from MyTable (nolock)
-- load data into it at your leisure (nobody else is waiting for this table or these pages)
insert #temp (ID, Name)
values (123, 'Timmy'),
(124, 'Jonny'),
(125, 'Sally')
-- Now that all the data is in SQL, copy it over to the real table. This runs much faster in most cases.
insert MyTable (ID, Name)
select ID, Name
from #temp
-- cleanup
drop table #temp
Also, your IDs should probably be identity(1,1) and you probably shouldn't be inserting them, in the vast majority of circumstances. Let SQL decide that stuff for you.
Oracle SQL Server Insert Multiple Rows
In a multitable insert, you insert computed rows derived from the rows returned from the evaluation of a subquery into one or more tables.
Unconditional INSERT ALL:- To add multiple rows to a table at once, you use the following form of the INSERT statement:
INSERT ALL
INTO table_name (column_list) VALUES (value_list_1)
INTO table_name (column_list) VALUES (value_list_2)
INTO table_name (column_list) VALUES (value_list_3)
...
INTO table_name (column_list) VALUES (value_list_n)
SELECT 1 FROM DUAL; -- SubQuery
Specify ALL followed by multiple insert_into_clauses to perform an unconditional multitable insert. Oracle Database executes each insert_into_clause once for each row returned by the subquery.
MySQL Server Insert Multiple Rows
INSERT INTO table_name (column_list)
VALUES
(value_list_1),
(value_list_2),
...
(value_list_n);
Single Row insert Query
INSERT INTO table_name (col1,col2) VALUES(val1,val2);
Created a table to insert multiple records at the same.
CREATE TABLE TEST
(
id numeric(10,0),
name varchar(40)
)
After that created a stored procedure to insert multiple records.
CREATE PROCEDURE AddMultiple
(
#category varchar(2500)
)
as
BEGIN
declare #categoryXML xml;
set #categoryXML = cast(#category as xml);
INSERT INTO TEST(id, name)
SELECT
x.v.value('#user','VARCHAR(50)'),
x.v.value('.','VARCHAR(50)')
FROM #categoryXML.nodes('/categories/category') x(v)
END
GO
Executed the procedure
EXEC AddMultiple #category = '<categories>
<category user="13284">1</category>
<category user="132">2</category>
</categories>';
Then checked by query the table.
select * from TEST;
